HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 790, 913, 538, 68 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 790, 913, 538, 68 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 790, 913, 538, 68 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 790, 913, 538, 68 is 1.
HCF(790, 913, 538, 68) = 1
HCF of 790, 913, 538, 68 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 790, 913, 538, 68 is 1.
Highest Common Factor of 790,913,538,68 is 1
Step 1: Since 913 > 790, we apply the division lemma to 913 and 790, to get
913 = 790 x 1 + 123
Step 2: Since the reminder 790 ≠ 0, we apply division lemma to 123 and 790, to get
790 = 123 x 6 + 52
Step 3: We consider the new divisor 123 and the new remainder 52, and apply the division lemma to get
123 = 52 x 2 + 19
We consider the new divisor 52 and the new remainder 19,and apply the division lemma to get
52 = 19 x 2 + 14
We consider the new divisor 19 and the new remainder 14,and apply the division lemma to get
19 = 14 x 1 + 5
We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get
14 = 5 x 2 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 790 and 913 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(19,14) = HCF(52,19) = HCF(123,52) = HCF(790,123) = HCF(913,790) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 538 > 1, we apply the division lemma to 538 and 1, to get
538 = 1 x 538 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 538 is 1
Notice that 1 = HCF(538,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 68 > 1, we apply the division lemma to 68 and 1, to get
68 = 1 x 68 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 68 is 1
Notice that 1 = HCF(68,1) .
